Yes the original pump access is there it is blocked off with a plate, what it would take to use it I am not sure. One thing I dont like is that where the fuel pump would end up I like it up on top where I can monitor it. Sitting here thinking about my rebuild and if you can actually use that original boss or not?????
Long Pause
Hmmmmmm
Long Pause oh crap go look at manual.
Manual no help go look at my photos of rebuild
OK OK maybe just maybe you can use another fuel pump but which one and what model I have no idea
but here goes oh and Thanks Greg for making me think!
Here you can see the original fuel pump mounting location on the left at the back!!
And here is a shot of my cam going in now remember this is not the original cam it is from Robert Henkel on Harsens Island. If you look close you can see 4 journals and then what looks like a journal for the fuel pump at the very front of the cam. So yes in a rebuild you may be able to use a stock type fuel pump but did CC have a journal on the stock cam no idea.
